We will use the motors and sensors in your toolkit to build the testbedSENSORSMOTORSSensor Arrangement

To the right of the cortex, attach the limit switch, bump switch, and line trackerTo the left of the cortex, attach the potentiometer and place any type of gear on the top

VEX CortexAll of our robotic systems are battery powered. The battery plugs in the end of the cortexnext to the ON/OFF switch

VEX Cortex - SensorsThe right side of the cortex has MOTOR INPUTSThe left side of the cortex has digital and analog SENSOR INPUTSVEX Cortex - MotorsFirst lets hook up a motor.

You need to use a MOTOR CONTROLLER whenever you connect a motor to the cortex. (To convert 2 wires into 3)

VEX Cortex - MotorsUse ports 2 or 3 for motor connections# 1 is for the CLAW!#2 is for the RIGHT motor#3 is for the LEFT motorNotice the Black wire plugs in next to the numbersMotorsThe motors are used to turn any axleattached to it. They are able to move inboth forward and reverse directions.

You need to use MOTOR SCREWSto attach the motors to your build.

Code for motors might look something like this:

VEX Cortex Digital SensorsDigital Sensors include:Limit Switch (Port 1)Bump Switch (Port 2)LED lights (Next Slide)

VEX Cortex Digital SensorsDigital Sensors include:Limit Switch (Port 1)Bump Switch (Port 2)LED lights (Port 12)

VEX Cortex Analog SensorsAnalog Sensors include:Line Tracker (Port 1)Potentiometer (Port 2)

Limit Switch Digital Port 1The limit Switch can be used to trigger an action when it is pressed. This can include: Start StopWait

A code using the limit switch would look like:

Bump Switch Digital Port 2

The bump Switch can be used to trigger an action when it is pressed. This can include: Start StopWait

A code using the bump switch would look like:

LED (any color) Digital Port 12

LEDs are lights! We have green,red, and yellow LEDs withour VEX kits

You need to use another switch to trigger the LEDs and turn themon or off

A code using the LEDs might look like:

Line Tracker Analog Port 1

The line tracker can be used to sense light and dark. Use this sensor to trigger other actions, such as Start StopWaitTurn on/off LEDs

A code using the line tracker would look like:

Potentiometer Analog Port 2

The Potentiometer can be used to sense movement in an arc. It does not move on its own, ratherit needs to be connected to a motor.

CAUTION: It is very sensitive, do NOTforce it to move or the internal parts will break.

A code using the Potentiometer would look like:
